DEVELOPMENT OF THEORY FOR KERNEL-SHELL EXTRACTION ON ROTATING INCLINE

Separation theory describing the motions of palm kernel and shell on rotating incline was analysed. Two series of differential equations, in order to obtain the dispatch angles of kernel and shell for the separation process were developed respectively. The differences in the motions and physical features of the particles formed the premise for separation. The results obtained from the theory showed a possibility of product separation within the approximate ranges of dispatch angles between 25 and 90 0 for kernels and shells on rotating incline, with specified slide limit, angular velocity and radius of the incline, and comparisons were made between the theoretical and experimental results. The dispatch angles obtained from both theory and experiment reasonably showed significant agreement and therefore suggested validity of the developed theory.
